This crankset is compatible with 3×7 and 3×8 drivetrains and provides wide range 50-39-34T gearing with a chain guard. It features a robust alloy construction, which makes it perfect for stress-free urban commuting from A to B. Shimano has also equipped this version with its renowned Hyperglide sprockets that incorporate specially positioned shift ramps and tooth profiles for improved chain control during shifting.

Technologies:

• Dual SIS Index: The SIS rear index shifting system was adopted at the front. With the index system at the front shifting operation is easier and more comfortable.
• HG HyperGlide: The distinctively designed HYPERGLIDE sprockets incorporate specially positioned shift ramps and tooth profiles for improved chain control during shifting. Fast and responsive indexed shifting is the result. The HG cassette sprocket, which was developed for the MTB 10-speed system, underwent comprehensive optimization to achieve super-highly efficient shifting.
